PurposeThe repatriation process often involves challenging and unexpected readjustment issues, leading to high turnover amongst repatriates. However, research has focussed on the re-entry decisions and experiences of company-assigned (CA) repatriates, whilst studies on self-initiated expatriates (SIEs) that repatriate back to their home countries (i.e. self-initiated repatriates (SIRs)) are limited, particularly in emerging transition economies. This study develops and tests a model to explain the factors influencing professional SIRs' turnover intentions and how repatriation readjustment affects their intentions in Vietnam.Design/methodology/approachThe data was collected from 445 Vietnamese professional SIRs who worked and/or studied for extended periods overseas and subsequently returned to Vietnam. Structural equation modelling (SEM) was used to analyse the data.FindingsResults indicate that both work and life repatriation adjustment difficulties have significant positive effects on turnover intentions, whilst only repatriation life adjustment difficulties have an indirect effect via life dissatisfaction. Further, cultural distance positively influences repatriation adjustment difficulties and turnover intentions. SIRs' on-the-job and off-the-job embeddedness negatively moderate the influence of repatriation work and life adjustment difficulties on turnover intentions, respectively.Originality/valueThe study develops a theoretical model explaining how repatriation difficulties impact the turnover intentions of SIRs, considering contextual factors including cultural distance and embeddedness. The research highlights the importance of job embeddedness as a form of social and organisational support for SIRs in managing psychological challenges related to repatriation, which can help reduce turnover and retain highly skilled talent. Additionally, the study extends repatriation research on an under-researched subgroup of SIEs, SIRs, in an under-researched emerging transition economy context.
